1* Amlogic Meson8, Meson8b and Meson8m2 Clock and Reset Unit
2
3The Amlogic Meson8 / Meson8b / Meson8m2 clock controller generates and
4supplies clock to various controllers within the SoC.
5
6Required Properties:
7
8- compatible: must be one of:
9	- "amlogic,meson8-clkc" for Meson8 (S802) SoCs
10	- "amlogic,meson8b-clkc" for Meson8 (S805) SoCs
11	- "amlogic,meson8m2-clkc" for Meson8m2 (S812) SoCs
12- #clock-cells: should be 1.
13- #reset-cells: should be 1.
14
15Parent node should have the following properties :
16- compatible: "amlogic,meson-hhi-sysctrl", "simple-mfd", "syscon"
17- reg: base address and size of the HHI system control register space.
18
19Each clock is assigned an identifier and client nodes can use this identifier
20to specify the clock which they consume. All available clocks are defined as
21preprocessor macros in the dt-bindings/clock/meson8b-clkc.h header and can be
22used in device tree sources.
23
24Similarly a preprocessor macro for each reset line is defined in
25dt-bindings/reset/amlogic,meson8b-clkc-reset.h (which can be used from the
26device tree sources).

29Example: Clock controller node:
30
31	clkc: clock-controller {
32		compatible = "amlogic,meson8b-clkc";
33		#clock-cells = <1>;
34		#reset-cells = <1>;
35	};
36
37
38Example: UART controller node that consumes the clock generated by the clock
39  controller:
40
41	uart_AO: serial@c81004c0 {
42		compatible = "amlogic,meson-uart";
43		reg = <0xc81004c0 0x14>;
44		interrupts = <0 90 1>;
45		clocks = <&clkc CLKID_CLK81>;
46	};
